Background: Previous studies have shown that epiretinal membranes (ERMs) may be associated with abnormal outer retinal anatomy. However, long-term morphological and functional results of pars plana vitrectomy (PPV) with ERM and internal limiting membrane (ILM) peeling in eyes with central bouquet (CB) alterations have not yet been investigated. Methods: In a retrospective, consecutive study all patients underwent best corrected visual acuity (BCVA) testing and spectral domain optical coherence tomography (SD-OCT) before and after a mean of 20 months (range 3–70 months) postoperatively. CB abnormalities and ERMs were classified according to Govetto’s staging systems. Results: Of the 67 eyes, 22 (34%) showed CB abnormalities at baseline. The mean BCVA increased from 0.42 at baseline to 0.20 LogMAR at final follow-up (p < 0.001). Neither ERM stage (p = 0.06) nor CB stage (p = 0.939) at baseline were significant predictors of vision improvement following surgery. Conclusions: Our results show that baseline BCVA, but not classification of CB changes and ERM at baseline, seems to be a useful predictor for functional outcomes following PPV with ERM and ILM peeling in the long-term.

Aim: To evaluate long term macular changes following pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for diabetic macular edema (DME) Methods: Forty eligible eyes of 37 patients were included in this retrospective study. Best corrected visual acuity (BCVA), central macular thickness (CMT) and 5-mm macular volume (5-MV) were examined preoperatively and at postoperative 1st, 2nd, 3rd, 6th, 12th, 24th months and final visits. Response to surgical treatment was considered as recurrence, reincrease and recovery of DME based on macular changes. Results: Mean follow-up time was 51.1±19.0 months following surgery. Recurrence (n=5) and reincrease (n=17) of DME was observed in 22 eyes (55%) and additional treatments were applied. Recovery of DME was observed in 18 eyes (45%). Preoperative and final visit mean BCVAs (logMAR) were 1.08±0.37 and 0.93±0.45, respectively (p=0.02). Preoperative and final visit mean CMTs were 514.74±155.65 µm and 281.87±112.58 µm, respectively (p<0.001). The 5-MV significantly decreased following surgery (8.18±1.57 mm3 to 6.52±1.39 mm3) (p<0.001). DME was present in 12 eyes (%30) at final visit. Conclusion: Although PPV with ILM peeling had an efficacy in DME management, this effect tends to decrease over time such that considerable amount of patients required additional treatment.

AimsWe aimed to investigate a novel optical coherence tomography (OCT) finding of outer retinal hyperreflective deposits (ORYDs) in patients with naïve diabetic macular oedema (DMO) seen after small gauge pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling. Furthermore, we evaluated the predictive value of ORYD for visual outcome over 24 months follow-up.MethodsRetrospective cohort study including 111 eyes from 111 patients with naïve DMO treated by PPV and ILM peeling with a follow-up of 24 months. OCT scans were analysed for the presence of ORYD 1 week and 1, 6, 12, 18 and 24 months after surgery. Change in baseline best-corrected visual acuity (BCVA) and central subfoveal thickness (CST) after surgery were measured over the follow-up period. Presence of ORYD was correlated with baseline characteristics and BCVA after 24 months.ResultsHundred and eleven eyes from 111 patients were included (mean age 67.5±14.8 years). ORYD was identified in the outer plexiform layer as hyperreflective deposits in 92 patients (82.8%) 7 days after surgery but it was not present before surgery. There was a significant reduction in the presence of ORYD. After 24 months ORYD disappeared in all cases (p<0.001).ConclusionsWe describe a novel OCT feature of ORYD present in the early postoperative phase in the majority of patients after PPV with ILM peeling for naïve DMO, disappearing over the postoperative course. These deposits might be a result of sudden desinflammation and could shed new light on the process of DMO resolution after operative intervention.

We conducted a meta-analysis of published retrospective studies and compared the effectiveness of pars plana vitrectomy with and without internal limiting membrane (ILM) peeling for idiopathic epiretinal membrane (IERM). The results revealed that patients in the IERM+ILM peeling group had better BCVA after surgery within 12 months than those in IERM peeling group. But patients in the IERM peeling group showed better BCVA in the 18th month. More retrospective studies or randomized controlled trials are required to investigate and compare the long-term effect of IERM removal with and without ILM peeling.

Purpose To describe the occurrence of massive macular edema and visual loss after indocyanine green-assisted (ICG) macular pucker surgery. Methods/Results A 74 years old female presented with a macular pucker and a hypertrophy of the retinal pigment epithelium (RPE) in her left eye. The preoperative visual acuity (VA) was 20/100. Surgery consisted of cataract extraction, lens implantation and standard pars plana vitrectomy with peeling of epiretinal tissue followed by the removal of the internal limiting membrane (ILM) remnants stained using a 0.05% ICG solution. One day after surgery, VA was counting fingers. There was an extensive macular edema and retinal thickening with hyperfluorescence during fluorescein angiography and pronounced autofluorescence using ICG filters. During follow up, the macular edema resolved completely, but VA decreased to 20/800 at six months postoperatively. There was a central scotoma and unstable fixation seen during microperimetry. Discussion This case report indicates that ICG might come into contact with bare retina if injected following removal of epiretinal membranes. Whether the observed RPE hypertrophy might have contributed to the pathogenesis of the adverse effect described remains hypothetical.

Abstract Background To evaluate the effect of internal limiting membrane (ILM) peeling surrounding macular holes (MH) for the function of retina by microperimetry-3(MP-3). Methods This is a prospective, cohort study which included patients with MHs who were treated by 23-gauge 3-port pars plana vitrectomy and ILM peeling with air tamponade. Color fundus photography, retinal optical coherence tomography and MP-3 were performed 1 week before, 1 and 4 months after the operation. In MP-3 examination, a customized follow-up pattern with 45 spots in the central 8° visual field was used. The spots corresponding to the retina surrounding macular holes were selected for comparison of pre- and post-operative function. Results We incuded 44 eyes of 44 patients with best corrected visual acuity (BCVA) of 1.06±0.40 (logMAR). All eyes achieved an anatomical success at 4 months. BCVA significantly improved at 1 month (0.53±0.30, P<0.01) and 4 months (0.31±0.24, P<0.01), respectively. Mean retinal sensitivity (MRS, dB) of the retina surrounding macular hole was 23.46±3.01 dB at baseline, and significantly increased at 1 month (26.25±2.31 dB, u=-4.88, P<0.01) and 4 months(27.14±2.45 dB, t=-6.29, P<0.01). Patients with increased MRS are significantly younger than those with deceased MRS (59.72±3.22 years vs. 65.60±8.19 years, P<0.01). After ILM peeling, the increasing extent of MRS was significantly higher in inferior and nasal retina than in superior and temporal retina at 1 and 4 months (P<0.05). Conclusion ILM peeling in normal retina will not decrease the retinal function in a short-term after surgery.

Abstract Purpose To evaluate the relevance of external limiting membrane (ELM) on the visual and morphological results in eyes with diabetic macular edema (DME) that underwent pars plana vitrectomy (PPV) with epiretinal membrane (ERM) and internal limiting membrane (ILM) peeling. Methods Medical records of patients with DME who underwent PPV at our unit between January 2017 and December 2019 were reviewed. We assessed preoperative and postoperative best-corrected visual acuity (BCVA), central macular thickness (CMT) using spectral domain OCT (optical coherence tomography). Exclusion criteria were previous PPV; incomplete data; concomitant diseases including retinal vein occlusion, age-related macular degeneration, uveitis; and a follow-up of less than 12 months. The surgeries were performed using 23- or 27-gauge vitrectomy. The ELM was graded depending on its configuration (grade 0 = intact, grade 1 to 3: disruption of varying extent). Results Ninety-nine eyes were enrolled. The postoperative follow up averaged 23.7 months. The preoperative and final BCVA averaged 0.71 ± 0.28 and 0.52 ± 0.3 logMAR, respectively (p = 0.002). The CMT averaged 515.2 ± 209.1 μm preoperatively and 327 ± 66.1 μm postoperatively (p = 0.001). Eyes with intact ELM (n = 8) had a significantly better BCVA compared to those with ELM disruption (0.28 ± 0.14 vs. 0.7 ± 0.25 logMAR, p = 0.01). The final CMT was similar among the groups (intact ELM: 317 ± 54.6 μm; ELM disruption: 334 ± 75.2, p = 0.31). Conclusions PPV with ERM and ILM peeling is an effective treatment of DME. Eyes with intact ELM preoperatively had a significantly better final visual outcome. To maximize the benefit for patients with DME we recommend early PPV as long as ELM is intact.
